Cimex lectularius L.
Bed bugs are flat, reddish-brown, oval insects up to 4 to 5 mm long or the size of an apple seed. Reddish and swollen after a blood meal. They are often active at night but will feed during the day if that is when you normally sleep. Bed bugs move relatively slow compared other insects like roaches or ants and they are not capable of jumping.
Often found in cracks and crevices, including mattress seems, sheets, furniture, behind baseboards, electrical outlet plates and picture frames. Often found in hotels, hospitals and schools where they can travel from room to room and in visitors’ luggage or other personal belongings such as purses, backpacks and briefcases.
Cockroaches can measure over 50 cm (2 in) length, while some tropical species grow to be larger than those found in other climates. Cockroaches have six legs, two antennae and some even have wings. However, most winged cockroaches are not particularly adept at flying.
Cockroaches can enter your home in many different ways, from the outside through cracks and crevices, vents, sewer and drain pipes. We even bring them in on products like grocery bags, boxes, purses and on our person!
Rats are instinctively wary of things new to their environment, including rat control measures such as traps and bait, and colonize in attics, burrows, under concrete and porches, in wall voids and other hard-to-reach places.
House mice are covered in short hair that is light brown or gray to black in color, with lighter bellies. Their ears and tail also bear hair, although much less than their bodies. Adult mice weigh approximately 12 to 30 grams and can grow up to 20 cm from the nose to the tip of the tail. Droppings are rod-shaped and pointed on both ends.
Ants can enter through even the tiniest cracks, seeking water and sweet or greasy food particles in the kitchen pantry or storeroom areas.
